Description of the Related Art Conventionally, a so-called hot plate welding method is used for a vehicle lamp in which a portion to be joined with a front lens also made of a thermoplastic synthetic resin is directly welded to a lamp body made of a thermoplastic synthetic resin. Has been proposed. Vehicle lighting device 51 manufactured by this method
As shown in FIG. 11, the welding portion 54 for welding and joining the lamp body 52 and the front lens 53 can be made thinner, and a wide effective area can be secured in a limited body space. It has the feature of. Also,
According to this hot plate welding method, a metal plate heated at a high temperature is sandwiched between a portion to be joined (welded portion 54) of a lamp body 52 and a front lens 53, which is a work, and a work that is thermally deformed or melted by heating the metal plate. The manufacturing method is such that the legs 52a on the lamp body 52 side and the legs 53a on the front lens 53 side, which are parts to be joined, are welded by pressure welding and integrated.

Are easily mixed into the welded portion 54 where the leg 52a on the lamp body 52 side and the leg 53a on the front lens 53 are joined, and the welded portion 54 is conspicuous. It didn't look good. In addition, since the legs 52a on the lamp body 52 side and the legs 53a on the front lens 53 side are melt-bonded at their respective tip portions, not only the reliability of the welding force is lowered, but also the processing portion is reduced. Has the disadvantage of becoming brittle. In addition, since a heated metal plate is used in the manufacturing process, there is a problem that the ambient temperature rises, the working environment of the operator is deteriorated, and the peripheral devices are adversely affected.

(Joint) 3a formed on the back surface periphery of front lens (member) 3
Of the lamp body 2 and the front part 3 of the front lens 3 can be thinned, and a wide effective area can be secured in a limited body space. It is what was constituted. In addition, a rear portion of the lamp body 2 communicates with the inside and outside of the lamp room 5 so as to communicate with the lamp room 5.
Vent holes 6 and 6 are provided to prevent fogging inside.

Drainage ribs 7 are formed on the outer periphery of the flange 2a so as to be folded back to the rear of the lamp body 2. This draining rib 7 has an action of shaking off water droplets whose tip portion hits the front lens 3 during running of the vehicle in rainy weather and spills backward from the side of the lamp body 2, and is configured at the rear of the lamp body 2. Water drops are prevented from entering the lamp chamber 5 from the ventilation holes 6. In addition, by forming the tip end of the water-removing rib 7 at an acute angle, the water drop-off action can be further improved.

For example, in the case where the opening peripheral portion of the lamp body 2 is large and the opening peripheral portion is formed so as to be turned back to the rear of the vehicle lamp 1, water droplets hitting the front lens 3 enter the ventilation holes 6. There is no fear, and there is no need to form the draining rib 7 above the vehicular lamp 1.

A draining rib 7 formed by folding the outer periphery of the flange 2a of the lamp body 2 is fitted into the lamp body 2 so that the side wall of the lamp body 2 can be fixed so as not to resonate.
Therefore, the lamp body 2 in which the depth of the lamp chamber 5 is formed deeply
Even in this case, resonance does not occur due to vibration of the front lens 3 on the side of the leg 3a, and frictional heat can be generated reliably.

FIG. Therefore, the surface of the front lens 3 as one of the workpieces W may be convexly curved as long as the leg 3a can vibrate and friction with the surface of the flange 2a. The present invention is not limited to the front lens 3 formed in a planar shape.

It shows another welding method . That is, the leg portion 3a of the front lens 3 is brought into pressure contact with the portion to be joined on the flange 2a side of the lamp body 2 to generate frictional heat, and the tip is melted to make the material on the lamp body 2 side. It is a fusion bonding between the two. Therefore, if the tip of the leg 3a is formed at an extremely sharp angle, the tip may bite into the flange 2a surface of the lamp body 2 during initial pressurization, making it difficult to vibrate. Therefore, as shown in FIGS. 10A and 10B, the tip is formed in a hemispherical shape or a conical shape in which the tip is curved, and is formed so as to generate smooth vibration on the surface of the flange 2a. It is desirable to do.
